Name:
Selesta's Tremendous Treasure Trove
Text:
Draw a card. Shuffle this card into its owner's deck as it resolves.
Treat this card in your removed area as two Treasures with different names. (It is still just one card, and all copies of this card share the same two names.)
Flavour:
"And then, one day, I was finally done. I had all the treasures of this world.", Selesta wrote in her autobiography. Later it turned out that 80% of them were just a fabrication, but the remaining 20% are still hidden somewhere. Really.
